Learn Basic String and Array Methods by Building a Music Player - Step 76

[abdullamaseeh123]

Tell us what’s happening: Can’t progress past step 76

Your code so far

In my code:

if (userData?.currentSong?.id === id) {
userData?.songCurrentTime = 0;
userData?.currentSong = null;
pauseSong()
setPlayerDisplay()
}

I keep getting this stupid error in the console:

SyntaxError: unknown: Support for the experimental syntax ‘optionalChainingAssign’ isn’t currently enabled (148:5):

146 | const deleteSong = (id) => {
147 | if (userData?.currentSong?.id === id) {

148 | userData?.songCurrentTime = 0;
| ^
149 | userData?.currentSong = null;
150 | pauseSong()
151 | setPlayerDisplay()

and I don’t know what to do. Somebody please help.

Welcome to the forum @abdullamaseeh123

I moved

@abdullamaseeh123

userData?.currentSong = null;

to the top of your code, removed the questions marks, and added semi colons, to the functions, and the step passed.

Not sure if this is a bug.

Happy coding

Thank you Teller for your help. I was also stuck at this step 76.
From your sugggestion, here is my understanding of the underlying rationale: the array of the a currently playing song cannot be undefined or null therefore, we do not need an optional chain (?.). Any thoughts?
